Stop that glare!
Are you so tired of trying to read your GPS in varying lighting conditions, with the glare driving you not to your destination, but merely crazy. Glare Stompers to the rescue.
The California firm that originally designed these visors for the TomTom Go GPS model has expanded to include models from Garmin, Magellan, Mavman and Sony plus every TomTom GPS product available. Priced at under $20 per visor, the GlareStomper, constructed of via black cordura nylon, blocks out ambient light that can wash out the GPS display by preventing sunlight to shine on the GPS from the tops and sides of the unit. Think of a three sided hood and you come close. The manufacturer says you get higher contrast, less glare, fewer reflections, and all around better viewing.
At these prices, it is certainly worth a shot.
